for Glenelg, MD
On arrival found unit locked out on e3, found condensate pump not operating and gfi was tripped. Reset gfi, tested pump/drain/system, unit operating normal. Customer signed up for service Agreement.
I cleaned the condensate pans and drain lines and flushed with hot water to remove debris and to make sure they were draining properly. I operated each unit on second stage cooling and confirmed/ set the proper flow rate and confirmed heat of rejection and delta temperatures across the coil. The filters were in very good condition. I checked the electrical wiring and electrical systems, all were within specification except for the run capacitor for each unit. I replaced these and retained the original ones to return to WF. I recommended installing Intellistart Modules on each unit to help protect the compressors. Customer asked me to email a quote. Both units are operating normal.
Found unit #2 with a blown fuse . Isolated the air handler and tested it . Then I isolated th airhandler with the thermostat and tested it . Then I added the safety switch and tested . Then I added the out door stat wire and it blew the fuse . Then I removed my wire from outdoor and tested and no short . So our low voltage short is located in outdoor . I looked over wires and did not see any burn marks but because of the snow falling I could not go into detail . Costumer has heat with Aux and we will need to come back to correct the short in the outdoor. Spoke with Alex and he said no charge for my visit but when we come back everything will be billable and I made costumer aware of this .
Fix wiring short. Unit #3 had a low voltage wiring short on the high pressure switch wire caused by an evaporator coil bracing bracket coming loose and falling on the wire bundles beneath it. There was only one wire that was damaged. I cut out the bad part and used a crimper tool to fix and then used electrical tape to insulate from weather. Unit operating normal. Customer also had a blown control fuse on unit #2. I replaced the fuse and used every technique to find a short but I could not. The system cycled in heat, auxiliary heat and defrost mode normal. I charged additional diagnostic time for this unit.
Fall pm on 12/20/18 On arrival set units to call for heat measured supply and return air temp measured voltage and amps inspected electrical connections checked drain and cleaned checked filters and replaced units operating normal at this time.
Performed pm on 2 geo systems. Replaced provided filters. Flushed out drains with brush and hot water. Tested condensate pump. Inspected blowers and coils cleanliness. Measured specs of capacitors and inspected contactors. Tightened all electrical connections. Ran aux heat. Measured amp draw and heat rise. Ran geos. Measured amperage of compressors, blowers, and loop pumps. Checked delta loop pressures and temps as well as delta air temp across Evap coils. Units are operating normal. Customer has steam humidifier in crawl space for vertical geo. Found humidifier shut off at Humidistat and all drain piping disconnected from humidifier. Inspected further and found all pvc piping to humidifier needs to be replaced and corrected. Could not test humidifier because of repairs needed.
